Role of provisional restorations in endodontic therapy

Abstract

Root-canal treatment can be carried out in single visit in vital, non-infected teeth, eliminating the need for dressing and provisionalization. Many clinical cases with infected canals require dressing with antibacterial medicaments in a multivisit treatment in which effective provisionalization for different periods of time becomes mandatory. Successful root-canal treatment requires effective mechanical and chemical debridement, elimination of bacteria and pulp tissue remnants and proper canal shaping to facilitate effective obturation. Lack of satisfactory temporary restorations during endodontic therapy ranked second amongst the contributing factors in continuing pain after the commencement of treatment. This review aims to provide an overview of the materials used for provisionalization during and immediately after endodontic treatment.

Marginal Leakage of Endodontic Temporary Restorative Materials around Access Cavities Prepared with Pre-Endodontic Composite Build-Up: An In Vitro Study

“…Temporary restorative materials should render the seal of the access cavity wall moisture-proof to prevent marginal leakage. They are also required to withstand masticatory stress, have excellent esthetic properties, be chemically and physically stable, and be easy to manipulate [2]. Therefore, hydraulic temporary restorative material, temporary stopping material, zinc oxide eugenol cement, glass-ionomer cement and resin-based temporary restorative material are currently used singly or in combination for temporary sealing [3].…”

Novel pyrazole‐clubbed thiophene derivatives via Gewald synthesis as antibacterial and anti‐inflammatory agents

“…[2] Their importance is highly growing due to their diverse pharmacological properties like antibacterial, antifungal, antimalarial, anti-inflammatory, and antiviral properties. [3][4][5] These derivatives are also extensively studied due to their antitubercular [6][7][8][9][10] activity. As this functionality has shown a relatively well response as an antitubercular agent, it has become a topic of interest in the field of research.…”

Novel Bioactive Zinc Phosphate Dental Cement with Low Irritation and Enhanced Microhardness

“…Many types of dental cements are available now in market, each with its own merits, though, the main dental cements in current use are zinc phosphate, polycarboxylate, glass-ionomer and resin composite [1]. Zinc phosphate cement is the oldest widely used dental cements; it is commonly used as permanent luting cement for metallic restorations, base materials and provisional restoration [2]. Its high compressive strength, its ability to create a very thin film mix, its slight setting shrinkage and its suitable working time are of great impact to clinical use.…”

“…Its high compressive strength, its ability to create a very thin film mix, its slight setting shrinkage and its suitable working time are of great impact to clinical use. However its low initial pH, may cause pulpal irritation immediately at the first hours after their application due to rapid drop in pH which increased gradually by time, especially when used under thin layer of remaining protective dentin layer [2,3].…”
